[PATCH v4 4/4] NEWS: release note the new hotplug enable/disable option on pci-root controller

[Ani Sinha]

A new 'target' subelement of the pci-root controller has been introduced having
a 'hotplug' property. This proprty can be used to turn off or turn on hotplug
capability of the devices plugged into the pci-root ports. This change release
notes this feature for the next release.

The new element can be used like this:

<controller type='pci' model='pci-root'>
   <target hotplug='off'/>
</controller>

This will turn off hotplug capability on the pci-root ports. To turn the
capability on, we set hotplug='on' above (which is also the default).
